Definitions

the invention relates to an arrangement for the identification of objects according to the preamble of claim 1.
patch fields which usually contain between 8 and 24 sockets.
patch cables can be inserted, the other end is either directly connected to a transmission unit, such as a data processing device, a network, a telecommunications device or other, or in turn plugged into another patch panel.
the invention has for its object to provide an arrangement for the identification and localization of essentially small objects, in particular connectors of data transmission cables in socket fields, which offers a simple structure even with high number and density, allows safe identification and localization and is very flexible ,
the invention relates to an arrangement for the identification of substantially small objects, which are provided with transponders for the identification of objects and at a destination a receiving unit for the identification of the objects is provided.
a receiver unit which is set up to receive different receiver frequencies, is assigned to each of a group of destinations for locating the items. These frequencies are selectively assigned to individual destinations and the radio signals emitted by the transponders can be received by the receiving unit at different frequencies.
a receiving unit is assigned to localize the objects of each of a group of destinations, which is set up to receive different reception frequencies. These frequencies are selectively associated with individual sockets of the socket field and the radio signals emitted by the transponders can be received by the receiving unit at different frequencies.
the transponders are preferably designed as RFID memory chips, which are attached directly to the cables of the connector or to the connectors themselves.
the RFID memory chips are preferably designed as a flexible film and glued to the cable or plug. They can also be integrated in the plug sheath or the cable.
a so-called reader which generates a high-frequency alternating field on the one hand to supply the RFID memory chips designated as transponders with energy when they are in the alternating field of the reader, and on the other hand receives the radiated from the transponders high frequency
the transponders are equipped with a resonant circuit that is tuned to a fixed frequency.
the payload information is usually found in the sidebands of the frequencies emitted by the RFID memory chip.
the simplicity of the structure of an RFID memory chip also means that the memory chip not only at the fixed frequency of Resonant circuit radiates energy, but also at multiples or anharmonic of the fundamental frequency.
the invention preferably uses this behavior of the RFID memory chip in order to selectively evaluate individual harmonics or anharmonics and their sidebands in the receiving unit.
the receiving unit i. a reader in an RFID system
the individual sockets of a Buchsenfeldes each assigned a specific reception frequency, it can be determined in this way, whether a particular socket is occupied by a plug. This makes it possible to precisely locate connectors besides identifying the information contained in the RFID memory chip.
the sockets of the socket field can be arranged as desired, for example in parallel rows one above the other. Furthermore, it is also possible to locate and identify at sub-sockets of multiple sockets, e.g. Quadruple sockets to make, because the space required by a receiving unit used in the invention is so small that localization can take place in a confined space. Since in each case only one reader is necessary for one or more groups of sockets, depending on the number of possible transmission frequencies of an RFID memory chip, a correspondingly high number of sockets can be addressed.
the invention uses the opposite approach, namely by evaluating a broad harmonic or anharmonic harmonic spectrum starting from a fundamental frequency. Since the effective reception range of the system according to the invention must be only a few centimeters, such "interference radiation" outside the system according to the invention is negligible.
the receiving unit For local detection of a connector in a socket field, the receiving unit preferably has the individual sockets of the socket field locally associated receiving resonant circuits whose received signals are fed to an evaluation circuit for assigning a connector to a socket.
the receiving resonant circuits are designed in particular as series resonant circuits of an antenna connected to the receiving unit. When using ferrite cores, each series resonant circuit requires only a few turns to obtain frequency-selective characteristics along with a capacitance.
the invention therefore uses different resonant frequencies in order to spatially allocate the transponders assigned to the connectors to the sockets in an antenna grid with differently designed oscillating circuits and to communicate with them individually via suitable evaluation electronics.
the invention requires only a single antenna whose series-connected coils are assigned to the sockets to be detected.
the invention makes it possible to achieve an exact spatial assignment of an RFID memory chip or a connector connected thereto to a plurality of sockets of a socket field, so that it can be determined with high certainty which socket is occupied by which plug.
the corresponding findings are preferably further processed in a patch management system.
the invention may be used in a variety of other applications where both identification and location of an article with respect to a particular destination is desired.
the invention may be used in any goods that need to be selectively assigned in a receiving magazine or the like (bearings, electrical sockets, mechanical, pneumatic, hydraulic or electrical connectors).
sample or the receptacle is provided with an RFID chip and the sample carrier contains a receiving unit, which is able to determine the location of each sample in the sample carrier.
the knowledge of the location allows a considerably simplified sample logistics
Figure 1 shows an RFID reader with a control unit 1, via which the RFID system is generally controlled.
the control unit 1 controls on the one hand a frequency unit 2, which is connected to the frequency input 3 of the reader 4 and on the other hand, a matching circuit 5.
the matching circuit 5 generates together with the respective switched resonant circuit formed of a coil of the antenna 6 and a capacitance, a high-frequency alternating field which is detected by transponders located in the near field of the transmitting antenna, rectified and used to power the transponder.
the reader shown in Figure 1 comprises an antenna unit 6 formed of a series connection of a plurality of coils L 1 - L N , each containing a few turns, each wound around a small ferrite core.
the individual coils L 1 - L N form together with the capacitor 7 resonant circuits on the Fundamental frequency, whose harmonic waves or anharmonic of the fundamental frequency are tuned.
the antenna unit 6 is connected to a receiver 9 in the reading device 4, which evaluates the frequency signals detected by the individual resonant circuits and outputs them as data signals at the output 10 of the reading device 4 for further processing.
the receiver 9 detects the high-frequency signal and its sidebands and outputs a data signal at the output 10. From the knowledge of the assignment of a receiving frequency to a single specific resonant circuit shows that in this case the oscillating circuit coil L3 has been addressed, and thus a connector was plugged into a the oscillating circuit coil L3 associated socket. From the identified data of the RFID memory chip can also be determined whether a "real" connector was plugged into the the oscillating circuit coil L3 associated socket.
the task of the matching circuit 5 is to alternately deliver the alternating field applied to the output 11 of the reading device 4 to the antenna 6 and the signal received by the antenna 6 to the input 12 of the reading device, switched capacitances determining the respective frequencies.
Figure 2 shows schematically the view of a multi-chamber socket, in which the frequencies F 0 , 2 x F 0 , 3 x F 0 , 4 x F 0 are each assigned to a specific socket chamber. This makes it easy to determine in which chamber socket a connector is inserted.
FIG. 3 shows a plurality of juxtaposed sockets of a patch panel, to each of which, for example at the bottom, series resonant circuits L1-L4 are assigned to a single antenna. Again, a localization and identification of an inserted connector is possible.
the transponder impedance affects the antenna series resonant circuit when approaching the antenna and can be considered as a series circuit with the resonant circuit.
the frequency unit determines the different carrier frequencies.
the control unit 1 switches and controls the multiplexer 13.
the output 14 of the matching circuit 5 is connected to the input 12 of the reading device 4.
the control unit 1 assigns via the frequency unit 2 to the reader different carrier frequencies, which are guided via the matching circuit 5 to the antenna 6, wherein the individual coils L 1 - L N together with the capacitances C 1 - C N form the respective effective resonant circuits.
the different Switched capacitances C 1 -C N which simplify the capacitor 7 in Fig. 1 correspond, compensate for the not required for the different resonant frequencies inductances.
the same resonant circuit arrangement then also receives the signals of the transponders, so that via the assignment of a coil L 1 - L N to the socket, a clear localization of a transponder with respect to a socket is achieved.
the evaluation of the output signals is the basis for a patch management system for multimedia connection technologies.
These connection techniques usually use multi-chamber systems with the ability to transmit multiple applications simultaneously via an interface.
